L-Tryptophan
Tryptophan is an organic compound with the chemical formula C11H12N2O2. It is one of the essential amino acids for the human body and an important precursor for auxin biosynthesis in plants. Its structure is similar to IAA. It is ubiquitous in higher plants and is also important in the human body. The neurotransmitter - the precursor of 5-hydroxytryptamine, can be used as nutritional supplements for pregnant women and special milk powder for infants, for niacin deficiency (pellagra), as a tranquilizer, can regulate mental rhythm, improve Sleep is also one of the raw materials of compound amino acid infusion.
